Should we give califorornia back to mexico???

Such question is rather political. I think it's best to let it be. Why bother to change the status quos? If California is handed back to Mexico, then possibly, it will start the domino effect -- more states will be claimed the sovereignty of some countries. Then what to do? There are still quite a few colonies belong to Britain today, now should they seek independence? A pain in the neck, isn't it?
